This is a simple risk analysis, and you should be comfortable with whatever decision you make now (and document it in case you have to justify it at a later date). If you do proceed with this cpu at least make a point to under-utilize your servers. </div><div><br></div><div>As an aside the 1000-user OVA is only for BE6K (and the TRCs it is based off + standalone ELM).

We don't allow CPU oversubscription for a reason (so the app can get the full core if need be), and any reservation an app may or may not set is for minimum processing power. Things don't tend to fall apart in an idle server. Where the processing really counts is under heavy load, which is most commonly associated with some other unexpected event (failover, call loop, etc). That isn't the time when you want to start seeing process cores because the system can't keep up with the incoming rate of signals. Those types of cascading failures are generally when exec's start calling each other, and everyone starts talking about root cause, design assurance, etc.</div><div><br></div><div><br><div apple-content-edited="true">
